Soprano 2.7.1 and 2.6.1 released

Soprano 2.7.1 and 2.6.1 are bugfix releases which fix a crash in the DBus communication.
2.7.1 is the recommended release for recent Linux distributions, 2.6.1 should be used on systems which still use Raptor 1.
 
Update:
Please DO NOT USE these releases as the appent fix they contain actually makes things worse. I am working on a real fix.
